RDP through VPN does not work now (used to work)

Hi,
I have a strange situation with remote desktop.  I had a single 2003 server, AD, DNS, DHCP, and RRAS, that needed to be taken down for a couple of days.  I installed a second server, promoted it, configured DNS, DHCP, and took the first server down for maintenance.  Then I brought the first server back on line, but did not have it run DHCP.  Both servers have a part of the scope, so this is not a problem.  Users used to be able to VPN in and connect to PCs/Servers on the network.  Then they could not, so I checked DNS records.  There were some conflicting entries, so I modified as necessary.  Everything works fine from the inside - ping by name, ping by IP, remote desktop.  VPN is able to connect from the outside, and ping internal resources by FQDN and ip.  I can connect to shares on the servers using UNC.  However, when I try and rdp into a server from outside through the VPN it just hangs.  I never get the logon screen, just the error message that says the connection to the remote computerwas broken....

Hi,
Thanks for the reply.  There are no errors in the RRAS machine, VPN is OK.  I have a laptop that I also use, and that has no problem establishing the RDP.  Very strange, maybe a packet size problem?
Thanks - Wayne

Hi,
It turns out the TCP/IP stack got messed up.  I ran the fix from Microsoft - KB299357 - How to reset Internet Protocol (TCP/IP) in Windows XP, and it works fine now.
I found the info in the followaing post at the end - http://www.experts-exchange.com/Networking/Misc/Q_21618230.htm

Thanks - Waynel
